Upper Wharf (Again)

Drop down to the ground after taking out the enemy below. You can sneak your way up to the security camera to the left, or simply blast it dead. Follow the doorway to the south to grab some items before following the signs that point to Jet Postal.

In the tubing ahead, watch for another security camera mounted along the right wall. You can hack this camera easily, then back away and let it call in security bots to take out the lead splicers in the immediate halls.
